Are there any pilots out there who have been on the KGNV-KATL route that could help a flight simulator enthusiast read a flight plan and duplicate the flight in FS2000?

I have questions such as what altitude to choose when I want to use a 737 series aircraft, how much fuel is needed (I'm having a difficult time reading the categories of fuel in the flight plan. This plan was for an RJ not a 737). Also, if there are any IFR minimums that I could use that are realistic so I can have a challenging flight, that would help too. Any suggestions would be appreciated, thanks.
